I got 100%... but.... what does this quiz mean?? It can't be based on land area, or Russia would be #1. It can't be based on economy size, or China would be #2. It can't be based on GDP per capita, or India and China wouldn't make the list at all. It can't be based on industrial exports, or China would be #1. It can't be based on industrial output, or Japan would be #2 and Russia wouldn't be on the list. So.... what is this based on? Some definition of what qualifies a country as "industrial" would also be helpful, though not as helpful as the overriding criteria for ranking.
